The 30-million-word-gap is a concept referring to the language disparity evidenced in low-income children compared to those coming from more affluent households. In recent research (Hirsh-Pasek et al., 2015) published in Psychological Science, verbal and non-verbal interactions between caregiver and child showed to be more influential for children’s language development than the volume of words spoken by a caregiver. This study was the impetus for further research by the Children and Families Lab.
The lab was awarded a grant to examine the communication foundation between caregivers and children in a sample of low-income, Spanish-speaking, Hispanic children. Dyadic, video-recorded interactions between caregivers and children are being coded for a variety of interaction characteristics such as joint attention. These interactions are being further analyzed for multiple language-based characteristics. This is an ongoing study.
